2. Call UserLoginService.DoLogin with username and password
   1. If LoginResult.State = LoginResultState.NEED_2FA then call UserLoginService.DoLogin, but now set Requires2FA to true and TwoFactorCode to SteamGuardAccount.GenerateSteamGuardCode value for request
   2. If LoginResult.State = LoginResultState.NEED_CAPTCHA then call UserLoginService.DoLogin, but now set RequiresCaptcha to true, CaptchaGID to CaptchaGID from response and CaptchaText to text from CAPTCHA at "https://steamcommunity.com/public/captcha.php?gid=" + CaptchaGID
3. Set received session to the SteamGuardAccount
4. Call SteamGuardAccount.FetchConfirmations to get array of confirmations
